HI @andrewatfornax,
Well, I have already seen it! Removed delivery capping, saved, but when I refreshed the page, the 0 gets back. Even now that you have remove id, if you click on campaigns, you will see that "0" is still there.
I'm starting to have my doubts in MySQL version 5.7. It may no accept null values. I will check it now, and get back to you.
Hi @andrewatfornax,
How the value of capping (when is not set) should be saved in DB?
If you see the following screenshot, the field type is INT, it doesn't accept null values and its Default value is "0"
